Asymmetric Quark/Antiquark Hadronization in ee Annihilation
نویسنده
چکیده
We point out that the fragmentation of a strange quark into nucleons versus antinucleons is not necessarily identical Dp=s(z;Q 2) 6= Dp=s(z;Q 2), even though the perturbative contributions from gluon splitting and evolution are p $ p symmetric. The observation of such asymmetries in the hadronization of strange and other heavy quarks can provide insight into the nonperturbative mechanisms underlying jet fragmentation in QCD.

KNO scaling in processes of electron - positron annihilation to hadrons
The charged particles multiplicity distribution in the KNO form is discussed in processes of ee annihilation at energies √ s 14 – 206.2 GeV. The experimental data are compared to data, obtained with Monte Carlo simulation in PYTHIA in the Lund quark string model. It is shown, that both experimental and simulated data are described by the same distribution function in the KNO form. It is shown, ...
متن کاملInvestigation of Quark–Antiquark Interaction Properties using Leading Particle Measurements in ee Annihilation
Measurements of heavy quark production in electron–positron collisions are used to analyse the strong interactions between quarks and anti-quarks. A scaling behaviour is observed in distributions of the rapidity change of D, B, and B mesons. From these distributions information is obtained on the hadron formation time, effective quark masses, and the potential between quark–antiquark pairs. Pre...

We point out that the fragmentation of a strange quark into nucleons versus antinucleons is not necessarily identical Dp/s(z,Q ) 6= Dp/s(z,Q ), even though the perturbative contributions from gluon splitting and evolution are p ↔ p symmetric. The observation of such asymmetries in the hadronization of strange and other heavy quarks can provide insight into the nonperturbative mechanisms underly...
متن کاملNew Physics at HERA: Implications for e+e− Scattering at LEP2
The impact of virtual leptoquark or R-parity breaking squark exchange as well as generic contact interactions on the production of quark–antiquark pairs in ee annihilation, in particular at LEP2, is summarized. An exciting possibility of sneutrino formation in ee scattering is also mentioned. Talk presented at the 5th International Workshop on “Deep Inelastic Scattering and QCD” (DIS ’97), Chic...
متن کاملCorrections to the Hadronic Cross Section Near Heavy Quark-Antiquark Thresholds in e+e− Annihilation
It is demonstrated how perturbative O(α2 s ) relativistic corrections to the non-relativistic stable heavy quark-antiquark production cross section in ee annihilation based on a Coulombic QCD potential can be systematically calculated using the concept of effective field theories. The O(αs) corrections from the relativistic energy-momentum relation, the relativistic phase space corrections and ...
